Trouble making prim detect correct position

[s3229002]

For some reason my prim detected the end position fine but then later on it doesn't work anymore. Here is my code:

 

integer on = TRUE;
vector pos;
vector startpos = <81.287,87.940,30.251>;
vector endpos = <81.787,84.690,30.451>;
key ToucherID;
integer channel_dialog;
integer listen_id;
list choice = ["1V", "3V", "5V"];
string msg = "Please choose a voltage value for battery:";

default
{
    state_entry()
    {
        llSetText("Touch to move voltage source",<0,1,0>,1);
        llListen(-20, "", "", "");
        channel_dialog = ( -1 *
(integer)("0x"+llGetSubString((string)llGetKey(),-5,-1)) );
    }

    listen(integer channel, string name, key id, string choice)
    {
        if(channel == -20)
        {
            llSetText("Reset!",<0,1,0>,1);
            llSetPos(startpos);
            llResetScript();
        }
        else if (choice == "1V")
        {
            llShout(30, "");
            llListenRemove(listen_id); //HERE WE ARE BEING RESPONSIBLE
        }
        else if (choice == "3V")
        {
            llShout(31, "");
            llListenRemove(listen_id); //HERE WE ARE BEING RESPONSIBLE
        }
        else if (choice == "5V")
        {
            llShout(32, "");
            llListenRemove(listen_id); //HERE WE ARE BEING RESPONSIBLE
        }
        else
        {
            llShout(33, "");
            llListenRemove(listen_id); //HERE WE ARE BEING RESPONSIBLE
        }
    }
   
    touch_start(integer x)
    {
        pos = llGetLocalPos();
       
        if (on == TRUE)
        {
           listen_id = llListen( channel_dialog, "", ToucherID, "");
           llSetPos(llGetLocalPos() + <0,0,0.2>);
           llRequestPermissions(llDetectedKey(0), PERMISSION_TAKE_CONTROLS);
           on = FALSE;
        }   
        else if(pos == endpos)
        {
            llSetText("Correct placement!",<0,1,0>,1);
            llSleep(3.0);
            llReleaseControls();
            llSetText(msg, <1,1,1>,1);
            llSleep(3.0);
            ToucherID = llDetectedKey(0);
        llDialog(ToucherID, msg, choice, channel_dialog);
        listen_id = llListen( channel_dialog, "", ToucherID, "");
        llSetTimerEvent(60); //HERE WE SET A TIME LIMIT
        }
        else if (on == FALSE)
        {
            llSetText("Wrong spot...",<0,1,0>,1);
            llSetPos(pos);
            llRequestPermissions(llDetectedKey(0), PERMISSION_TAKE_CONTROLS);
            llReleaseControls();
            on = FALSE;
        }
    }
   
    run_time_permissions(integer perm)
    {
        integer controls = CONTROL_FWD | CONTROL_BACK |
             CONTROL_ROT_LEFT | CONTROL_ROT_RIGHT;
        if(perm & PERMISSION_TAKE_CONTROLS)
        {
            llTakeControls(controls, TRUE, FALSE);
        }
    }
   
    control(key id, integer level, integer edge)
    {
        integer button = level;
        if(button & CONTROL_FWD)
        {
            llSetPos(llGetLocalPos()+<0,-0.25,0>);
        }
        if(button & CONTROL_BACK)
        {
            llSetPos(llGetLocalPos()+<0,0.25,0>);
        }
        if(button & CONTROL_ROT_LEFT)
        {
            llSetPos(llGetLocalPos()+<0.25,0,0>);
        }
        if(button & CONTROL_ROT_RIGHT)
        {
            llSetPos(llGetLocalPos()+<-0.25,0,0>);
        }
    }
   
    timer()
    { //TIME?S UP!
        llListenRemove(listen_id);
        //llWhisper(0, "Times up.");
        llSetTimerEvent(0.0); //Stop the timer from being called repeatedly
    }
}

It would help if you explained what you're trying to achieve so we didn't have to try to work it out from your code.  At least you pasted that so we can.

"else if(pos == endpos)" is VERY precise when "vector endpos = <81.787,84.690,30.451>;"

It has to be within a millimetre in all three dimensions.  Round and test within bounds rather than for a single value.

Good to see you back again, s32.  I assume that this is part of the circuit board simulation project that you described the last time you posted here.  Peter's right.  Treat this like a real circuit board.  You get the component in roughly the right place and its pins will line up well enough to plug it in.  Just figure out how you're going to write

if (pos == close_enough_to_endpos)

and you've got it made.  Hint:   llVecDist .

Hey guys,

 

I figured out that if I re-created my prims and start from scratch the positions work perfectly. Problem solved! Thanks anyway.

It's worse than that pete... it has to be EXACT... some rounding in the intial position or the region save state on a reset and it'll never hit. even if it's less than an an angstrom away from the target position.

if you want high precision and still some sane flexibility, llTarget and the at_target event

 

the other option is check if position is less than a certain value from your target position
